Max external monitors for late 2013 15" MBP?

[tmoney468]

Quick question guys, I have the Dell P2715Q 4k external monitor, I was wondering, is it possible to add another ultra-wide monitor (3440x1440) to my setup? So in short, have my MBP lid closed and have the 4K monitor + an ultra wide monitor as a dual monitor setup?

MacBook Pro (Retina, 15-inch, Late 2013)
2.6 GHz Intel Core i7
Intel Iris Pro + 750M graphics

I think so, i have 3 external monitors and everything works fine.

Careful with high sierra, i couldn't work with external monitors on it, the laptop got really laggy, after downgrading to sierra everything works fine
